By working with the given percentage, we conclude that:
First, we know that the initial investment is $7,500, and at the end of the year, it increases by 7.4%.
Then to get the increase in dollars, we need to find the 7.4% of $7,500, so we can find the percentage by computing the following equation:
$7500*(7.4%/100%) = $7500*0.074 = $555
Then we conclude that the increase in dollars is $555.
To know how much money was in her account at the end of the year, we just need to add the initial investment plus the above we found above, it will give:
$7500 + $555 = $8055
We conclude that at the end of the year, the amount in her account was $8055.
